ACI SP-180-98

During the ACI Spring Convention 1997, ACI Committee 408, Bond and Developemnt of Reinforcement, organized four sessions intending to assess the state-of-the-art in bond research, practical applications, and code developemnts. The sessions were co-sponsored by the Technical Group 2/5 - Bond Models of the Comite Euro-Internationale du Beton (CEB). The Symposium drew a very large number of abstracts from its open call for papers. The final selection of the abstracts was based on both the technical merit and relevance of the topic. The majority of the presenters have provided written contributions to this volume, which is intended to serve as the third major conference on bond research in the past 15 years. The first major conference was organized in Scotland, UK, in 1982, and the second in Riga, Latvia, in 1992. Although these conferences are not formally connected, their intent has been to provide a forum for discussion of advanced mechanistic bond models, experimental research aimed both at model verification and development of design provisions, and practical design problems associated with bond and development of reinforcement. The sessions held in Seattle, Washington, were organized into a symposium honoring Dr. Peter Gergely, a long-time member of Committee 408, who had recently passed away. This volume is dedicated to Dr. Peter Gergely, an outstanding engineer, educator and friend whose "joie de vivre" will not be forgotten by those who came into contact with him.
